Fodor's Expert Review Museo di Arte Sacra
Massa Marittima
Art Museum
In the converted convent church of San Pietro all'Orto, this museum houses a large number of medieval paintings and sculptures gathered from churches in and around Massa Marittima. Perhaps the most important piece, Ambrogio Lorenzetti's early-14th-century Maestà, was discovered in the storage room of the church in 1866.
